It simulates a seal learning to balance a pole on its nose, illustrating unsupervised learning in a pain of hidden layered neural nets. The specifics come from the 1986 dissertation of Charles Anderson at the University of Massachusetts ("Learning and Problem Solving With Multilayer Connectionist Systems"). The demo, however doesn't go into a lot of detail on the implementation, but is fun to watch. Assuming you can get at a NeXT, the program is located in the /NextDeveloper/Demos directory.
